Beverage bottle

ABSTRACT

A dual chambered beverage bottle made of synthetic resin is described. The bottle has a cylindrical body member that is divided by a partition wall perpendicularly disposed in the body member to form separate chambers, so that it is possible to contain two different drinks in the chambers. The beverage bottle has a cup which is secured to the bottle spout member as a cap in a substantially liquid-tight relationship, so that users do not need a separate cup to receive drinks poured out of the bottle and may enjoy greatly enhanced convenience when traveling or engaging in sports activities.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a beverage bottle, andmore particularly to a synthetic resin bottle, which has a cylindricalbody, dual chambers divided by a partition wall perpendicularly disposedin the cylindrical body, and a cup secured to the bottle spout member asa cap in a substantially liquid-tight relationship.

[0003] 2. Description of the Prior Art

[0004] As well known to those skilled in the art, aluminum cans andglass bottles are used and merchandised to contain drinks currently.However, because aluminum and glass are expensive materials, a syntheticresin is frequently employed as a material to mold beverage bottles allover the world.

[0005] In FIG. 1, a conventional beverage bottle is illustrated. Thebottle includes a generally cylindrical body member 1 and has a spoutmember 2 at the upper end of the body member 1. The spout member 2 hasan external thread 3 on its outer periphery that can be engaged with acooperative thread 5 inside of a cap 4. The spout member 2 also has anannular peripheral flange 6 outwardly extending from the underside ofthe external thread 3 for stopping an excessive rotation of the cap 4.The annular peripheral flange 6 also may be used as an easy-to-griphandle by a user.

[0006] However, the conventional beverage bottle has some problems asdescribed below.

[0007] One problem is that the bottle needs a separate cup to receivedrinks poured out of the bottle by a user, which causes the user'sinconvenience. Another problem is that the size of the cap of the bottleis relatively small, so that it is difficult to open the cap with theuser's fingers. Another problem is that the bottle has a single chamberfor storing a drink, which makes it impossible to contain two differentliquids.

[0008] In order to solve the problems, Korean Pat. Appln. No. 2000-28791applied by this applicant discloses “beverage container with selectiveopeners and dual storing chambers”, in which the container has dualchambers divided by a partition wall, so as to make it possible to holdtwo different liquids. However, the configuration disclosed in thepatent application is problematic, in that it can be applied to can typebeverage containers, but cannot be applied to synthetic beveragecontainers that is most widely utilized currently.

SUMMARY OF THE INVENTION

[0009] Accordingly, the present invention has been made keeping in mindthe above problems occurring in the prior art, and an object of thepresent invention is to provide a beverage bottle, which is providedwith one or more chambers and a double-walled cap, thereby containingone or more drinks in the beverage bottle, and allowing its cap toserving as a cup as well as a cap so as to eliminate the inconvenienceof carrying a cup during sports activities, tours or travels.

[0010] In order to accomplish the above object, the present inventionprovides a beverage bottle, comprising: a bottle body member having acylindrical shape; a spout member positioned on the upper end of thebottle body member, the spout member including an external thread on itsouter periphery and an annular peripheral flange outwardly extendingfrom the underside of the external thread for stopping the excessiverotation of a cap, the annular peripheral flange being adapted to beused as an easy-to-grip handle by users; a double-walled cap providedwith inner and outer walls, the inner wall having a cooperative threadtherein for being engaged with the external thread of the spout member,the outer wall being formed to serve as a cup to receive a beveragepoured out of the bottle body member; and a circumferential sealingstrap adapted to be adhered around the entire circumference of thebottle body member in the region that the edge of the outer wall and theouter surface of the bottle body member are engaged, the sealing strapincluding a separation line placed in the longitudinal direction of thestrap, whereby users can apply a shear stress to the separation line ofthe strap so as to tear the strap along the line and to separate the capfrom the bottle body member.

[0011] The body member is separated into an upper section and a lowersection.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Reference now should be made to the drawings, in which the samereference numerals are used throughout the different drawings todesignate the same or similar components.

[0019] First Embodiment

[0020] In the FIGS. 1 and 2, a first embodiment of the beverage bottleof the invention is illustrated. In this embodiment, the bottle includesa cylindrical body member 1 and a spout member 2 on the upper end of thebody member 1. The spout member 2 includes an external thread 3 on itsouter periphery and an annular peripheral flange 6 outwardly extendingfrom the underside of the external thread 3 for stopping the excessiverotation of a cap 4. The annular peripheral flange 6 is adapted to beused as an easy-to-grip handle by users.

[0021] The beverage bottle has a double-walled cap that is provided withinner and outer walls 4 a and 4 b. The inner wall 4 a has a cooperativethread 5 therein for being engaged with the external thread 3 of thespout member 2, and the outer wall 4 b is formed to serve as a cup toreceive a beverage poured out of the bottle body member 1.

[0022] The beverage bottle also has a circumferential sealing strap 7that is adapted to be adhered around the entire circumference of thebottle body member 1 in the region that the edge of the outer wall 4 band the outer surface of the bottle body member 1 are engaged. Thesealing strap 7 includes a separation line 8 that is placed in thelongitudinal direction of the strap 7. Thereby users can apply a shearstress to the separation line 8 of the strap 7 so as to tear the strap 7along the line 8 and to separate the cap 4 from the bottle body member1.

[0023] Second Embodiment

[0024] In the FIGS. 3 and 4, a second embodiment of the beverage bottleof the invention is illustrated. In this embodiment, the body member 1is separated into an upper section la and a lower section 1 b.

[0025] The dual chambered body member 1 may be formed by an biaxial blowmolding in which a preform having a wall may be expanded by an biaxialblowing process, so that the preform is biaxially expanded to form theupper section la and the lower section 1 b respectively.

[0026] Alternatively, the dual chambered body member 1 may be formed bybonding two half-bottle bodies that are symmetrically the same in shaperespectively. The bonding of both flat bottom surfaces of the halfbodies may be achieved through a supersonic wave bonding process or byan adhesive such as a urethane adhesive, a hot-melt adhesive(polyamides) or an acrylic adhesive (TGA) that may be cured byultraviolet rays in a short exposure time without environmentalpollution.

[0027] Both caps 4 of the bottle may be identical for permitting simpleand inexpensive construction.

[0028] It is desirable that the one end cap 4 of the bottle has samediameter as that of the bottle body member 1 and flat bottom surface sothat the bottle may have an increased stability when standing in anupright position.

[0029] A comparison of FIGS. 1 and 4 makes readily apparent theadvantages of the present invention. The beverage bottle of theinvention has a cup that is secured to the bottle spout member as a capin a substantially liquid-tight fashion so that a user does not need aseparate cup to receive drinks poured out of the bottle. The body memberhas dual chambers divided by a partition wall, so that the bottle mayhold two different beverages. Customers can enjoy greatly enhancedflavor retention of one or more beverages. Finally, the beverage bottleof the invention is easily opened by simply twisting the cap 4 againstthe body member 1, wherein the separation line 8 along the strap 7 isparted to separate the cap 4 from the bottle body member 1.

[0030] Although the preferred embodiments of the present invention havebeen disclosed for illustrative purposes, those skilled in the art willappreciate that various modifications, additions and substitutions arepossible, without departing from the scope and spirit of the inventionas disclosed in the accompanying claims.
